Description

Running Eden with QEMU 9.0 and QEMU 4.2.1 failed due to deprecated parameters.

The prerequisites in the Eden says at least QEMU 4.x or higher version is required, but using QEMU 4.2.1 and 9.0.1 versions resulted in a failure during eden setup.

To make it works on macOS I also had to modify the following:

pkg/defaults/defaults.go

126 + 	DefaultQemuAccelDarwinArm64 = "-machine virt,accel=hvf,usb=off,dump-guest-core=on -cpu host "
